Acids:
Wine – cooking/drinking

Bases:
Baking soda – cooking/cleaning
Coffee – cooking/eating
Soap – cleaning
Explain why an understanding of pH is particularly important to gardeners and farmers.
It is important that gardeners and farmers have an understanding of pH levels as soil pH levels can have a dramatic effect on nutrient availability. pH testing on soils may indicate an imbalance of the pH levels. These indicators include:
Plants not performing well, even with the addition of fertiliser
Iron deficiency
Flowering hydrangeas (blue flowers are produced in soil with a pH of 6 or less and pink flowers are produced in soil with a pH of 6.8 or over)
